Attempting to loot a throne while confused and carrying gold generates a throne room monster and deposits a random amount of your gold in its inventory ("The exchequer accepts your contribution"). However, if there is a chest on the level, the gold is put in that without creating a monster ("Thank you for your contribution to reduce the debt"). Large boxes do not count. The throne is not destroyed in the process.

In both cases, your constitution is abused. Items in inventory are NOT
at risk of explosion.

9

If you have any gold in your main inventory, it's all taken away.

"You notice you have no gold!"

Otherwise, no effect.

"You feel a strange sensation."

10

d10 throneroom monsters appear around you.

"Thy audience hath been summoned, <Sire/Dame>!"

11

If your Luck is strictly positive, you are blinded for 250 to 349 (more)
turns; otherwise, your inventory is randomly cursed (as for a
"malignant aura").

"A curse upon thee for sitting upon this most holy throne!"

12

If you have negative Luck, you wake all monsters on the level.

"You feel threatened."

Otherwise, you are teleported within the level.

"You feel a wrenching sensation."

13

You are confused for 15+d7 (more) turns.

"Your mind turns into a pretzel!"

Whether anything happened or not, if you are still sitting on the
throne (haven't teleported away), there is a 1/3 chance that the
throne will then disappear.

"The throne vanishes in a puff of logic."

The phrase "vanishes in a puff of logic," is taken from the Douglas Adams comedy series, The Hitchhiker's Guide to the Galaxy. To be precise, it comes from an aside where humanity convinces God that He doesn't exist, and God "vanishes in a puff of logic."

It is also possible to #kick a throne, in the hopes of knocking loose some gold and valuable gems. However, the potential advantages of sitting on a throne far outweigh the benefits of additional treasure.

If you have negative luck, or treasure has previously been kicked from the throne, there is a 1/3 chance of destroying the throne, which will exercisedexterity and leave behind d200 gold pieces.

"CRASH! You destroy the throne."

"CRASH! You destroy it." (if blind)

If you have positive luck, and treasure has not already been kicked from the throne, there is a 1/3 chance of dislodging some loot: 201 to 500 gold pieces, and a number of gems equal to your luck + 1, up to a maximum of 6.

"You kick loose some ornamental coins and gems!"

"You kick something loose!" (if blind)

If neither of the above effects occur, there is a 1/4 chance that you may trigger a (hidden, and untriggerable any other way) trap door.

"The floor opens up under you!" followed by "The hole in the ceiling above you closes up."

If you didn't get any of the above, you get a hurt foot; your dexterity and strength are abused, there is a 1/3 chance of your right leg being hurt for 6 to 10 turns, and you lose d5 HP (d3 HP if your constitution is greater than 15).

If the throne causes you to teleport and you have teleport control, you should choose to teleport to a different square rather than remain on the throne. This eliminates the chance that the throne will disappear from that use.

Confused looting (with gold and without a chest) is fairly safe and cheap. It can be a great source of dragons and things that they provide (scales, corpses (resistances), loot, pets).

If you have positive luck, kicking the throne to obtain the gems and gold is always safe (except from a bones), as the throne can always be looted exactly once in this way. Because the number of gems created this way is not random, it can be used to determine your luck if it is under 5. Additionally, because a non-cursed luck stone will increase your luck by 3, it is possible to identify a gray stone as luckstone if your base luck is 0; if you are able to knock loose 4 gems, then you are carrying a luckstone.

In SLASH'EM, sitting on a throne can only grant a wish if your luck is at least 8. If your luck is not high enough, your luck will be increased by 5 rather than by 1. Otherwise thrones behave exactly as in Vanilla.

Methought I saw the footsteps of a throne
Which mists and vapours from mine eyes did shroud--
Nor view of who might sit thereon allowed;
But all the steps and ground about were strown
With sights the ruefullest that flesh and bone
Ever put on; a miserable crowd,
Sick, hale, old, young, who cried before that cloud,
"Thou art our king,
O Death! to thee we groan."
Those steps I clomb; the mists before me gave
Smooth way; and I beheld the face of one
Sleeping alone within a mossy cave,
With her face up to heaven; that seemed to have
Pleasing remembrance of a thought foregone;
A lovely Beauty in a summer grave!
